Which is better sew in or crochet?
Crochet braids are more affordable than sew-ins. Whether you install it yourself or have it installed, the hair and the labor can eat away at your money, especially if you buy good, quality hair to use. With crochet braids you are saving on the hair for sure.
How long should you wait between crochet braids?
Typically crochet braids last between four to six weeks, and you can always leave the center in a little longer and touch up the front (aka the parameters of your hairline) so it looks fresh.
